HEATn-NG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 702,219, dated J une '410, 1902.

l i, Application tiled March 6. 1902. Serial No. 96,983. (No modelJ To a/ZYZ whom it 11i/ay concern):

Be it known that I, MANANDER M. JOHNSON, a citizen of the UnitedStates, residing at Clay Center, in the county ef Clay and State of Nebraska, have invented certain new and useful Improvements in Heating Apparatus; and

I do declare the 'following to be a full, clear,

and exact description of the invention, such y as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to heating-chambers and means for heating the same.

The object of the invention vis to provide a combined hot-water and hot-air heating device for incubatore, broeders, duc., which is simple of construction, comparatively inexpensive ofproduction, eiicient in use, and

so constructed as to maintain a substantially equal temperature at all parts of the heatingchamber.

The invention consists of cert-ain novel features and parts and combinations of the same, as will be] fully described hereinafter aud then pointed outin the claims..

A practical embodiment of the invention is represented in the accompanying drawings,

in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a horizontal section through the heating-cham ber of an incubator, showing the application of the invention thereto. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a vertical transverse section on line 3 3 of Fig. 1. line 4 4 of Fig. 1, illustrating the telescopic construction of the outlet-pipe.

Referring now more particu'larl'y -to the `drawin gs, the numeral 1 represents a heatinge chamber, which may be embodied in an incubator, brooder or other device, or may be -V used for any desired purpose for which it is adapted. Supported alongside thischamber 4lis a hot-air heater 2, consisting in the present instance of an oil-lamp, and located .above this heater is a hot-air drum 3, in which is arranged a iue 3 for conveying the hot air to the heating system embodying the present ,4 invention. -The parts of the said system are disposed in the upper portion ofthe chamber front and rear of said chamber.

1, and consist of longitudinal water-circulating pipes 4 and 5, which are arranged at the The ends' Fig. 4 is a sectional View on.

, which leads to one end of a heat-radiating pipe ordrum 10. This drum lextendsalongside the pipe 5 and is provided at its opposite end with an outlet 11, by which the hot air,

after circulating through the pipes 8, 9, 9,

and 10, passes out tothe atmosphere.

In order to secure the eective continuous circulation of the water through the pipes 4,

5, 6, and 7, the pipe 6 is connected at the top l and the pipe 7 at the bottom of the pipes4 and 5, so as to have arise and fall of the water at opposite portions of the. conduit. By.

this means the water discharging from the pipe 7 into the bottom of pipe 4 is caused to rise in said pipe 7 on being heated by radiation from the. pipe 8 and to pass therefrom into pipe 6,.`w`hereby a circulation through the hot-water pipes is created. It will of course be understood that the water tion transfers the greater portiouof its heat to the pipes 5, l, and 7, thus heating all sides of the chamber, and that upon the return of the water to the pipe 4 it is reheated and the is heated from the pipe 8 and on its circula rising action reproduced, and this iscontinued as long as thedevice is kept in operation. It will be readily seen ,from the foregoing description that as the water in the pipe 4 is heated directly from the pipe 8 a greater amount of heat is radiated from said pipe 4 than from the pipe 5. This is, however, com` pensated for by arranging the drum l0 adjacent to the pipe, so that an approximately equal amount of heat will be supplied at the front and rear of the chamber. The amount of heat thrown out at the sides of the chamber is substantially the same, since the pipe 7, though conducting water of a lowertem perature than the pipe 6, is located closer tothe heater, whereby the dierence.: in the amount of heat radiated by the two pipes G and 7 is compensated for.

The drum 10 is made adjustable toward and from the pipe by the two telescopic sections 9 and 9b and the pipe 1l of two telescopic angular sections, so that said drum 1.0 may be adjusted to the frontor rearin order that the amount of heat radiated atthe rear of the chamber may be varied to correspond .approximately to the amount of heat being supplied'at the front of the chamber by the pipe 4, thus insuring an even temperature on all sides of the chamber. By this means after the pipes have been mounted in the chamber and the heater set in operation the drum' 10 may be adjusted back and forth until set in the proper position for regulating the supply of heat to secure an even temperature.

In practice pipes 4, 5, 6, and 7 are preferably made of copper and pipes9', 9",.an'd 10 of galvanized sheet iron or steel,` thus securing a saving in the cost of material overheaty'ers employing copper tanks and at the same time providing a simpler and more efficient apparatus.y

From the foregoin'gfdescription, taken in connection with the accompanying drawings,

it is thought that the construction,'operation,

. and advantages of my improved heating apparatus will be readily apparent without requiring a more extended explanation'.

It will be seen that the device is simple of construction', efficient in operation, comparatively inexpensive of production, and adapted for heating incubators, broeders, and ,other forms of heaters.
